JOHN RUSH, OF NORWICH, CONNECTICUT, ASSIGNOR T SGHWAR-ZENBAGH HUBER(30., OF WEST jHOBOKEN, NEW JEIIFtSEY- "TAKE-Ur AND GUIDE FOR, SHUTTLES,

Application filed January 30, 1924. Serial No. GfiQMf)v To all whom itmay concern:

Be it known that 1, JOHN Rusn, a citizen of the United States, and aresident of Norwich, in the countyof New London and State ofConnecticut, have inventeda new and Improved Take-Up and Guide forShuttles, of which the following is a full,

provide a take-up and, guide for shuttles l erly.

which will readily co-act with automatic mechanism forsupplyingnewquills to the shuttle whereby the thread from the new quillwill be automatically threaded prop- In the accompanying drawing} Figure1 is a fragmentary top plan view showing one end of a shuttle with anembodiment of the invention applied thereto.

Figure 2 is a side view of the structure shown in Figure 1. 1

Figure 3 is a longitudinal vertical sectional view through Figure 1,approximately on line 33. i a I Figure 4 is a transverse sectional viewthrough. Figure 2, approximately on line Figure 5 is a transversesectional view through Figure 2, approximately on line Figure 6 is ,atransverse sectional view through Figure 2, approximately on line 6-6. p

Figure 7 is a longitudinal horizontal sectional view through Figure 3approximately on lineT- T. a

Figure 8 is a detail perspective view showing a thread guide embodyingcertain features of the invention.

Referring to the accompanying drawing by numerals, 1 indicates a shuttlewhich is of the usual type and cut away at the front for receiving thethread guiding structure Qandl the take-up structure 3. The threadguiding structure 2 is locked in position by any suitable means, as forinstance, the screw 4. The thread guiding structure 2 may be made in onepiece or in a number of pieces secured together and when completedincludes an end member 5, which acts to hold the thread which comes fromthe quill in place and also partially asa guide for the thread 6 as ittravels to the take-up structure 3 and from thence out through the eye7. The end member 5 and the vertical side wall 8 merge into a top plate9 which is somewhat rounded as indicated in Figure 3 and whichterminates beyond the thread guide 2. Preferably, a pair of dependingmembers 10 and 11 extend from the end of the top plate 9, said membersbeing spaced apart and acting as guides for guiding the thread as itmoves over the outer surface of the end member 5, the top plate 9 and tothe guide 2. The top plate 9 isprovided with a dependin section 12having a curved edge 13 co-acting with the curved edge 14 of the shuttle1 for presenting a guide for the thread as it moves to the eye 7. Itwill be noted that a projection 15 extends into the eye 7 to prevent theaccidental return of the thread through the slot 16.

In operation, when it is desired to correctly place thethread in theguide 2, the thread is moved down over the outer surface of the endmember 5 and also over the guide to members or prongs 10 and 11whereupon it will pass into the slot 16 and at the same time will slipoff the end members 10 and 11 and be engaged by'the tension structure 3;.As the thread is moved further down the slot 16, it will automaticallyenter the eye 7 as indicated in Figure 2 whereupon it is in correctposition for use.

In order that the thread. may remain at the upper part of the threadguideQ, a pair of forwardly extending fingers 17 and 18 are provided,said fingers being connected with the bottom part of the thread guideThe forward ends of these fingers are beneath and near the prongs 10 and11 so that as the thread falls off these prongs it will fall on thesefingers and be guided over to a point against the tension member 3. Thistension member consists preferablly of a plurality of fingers 19pivotally mounted on the rod or pin 20 carried by the shuttle 1.

Preferably, these pins are all Secured to a 0 tubular member 21 so thatthey will move in unison. Each of these fingers is provided with apartially closed hook 22 which almost forms an eye though it issufficiently open to permit the thread to enter as indicated in Figure 3where the thread normally remains during the operation of the shuttle.

In order that a proper tension may be provided, an arm 23 is soldered orotherwise rigidly secured to the tubular member 2] and to the upper endof this arm is connected one end of the rubber band 24, the opposite endextending through the aperture 25 to a point near the exterior sur' faceof the shuttle 1. Preferably, the aperture 25 is comparatively small toa point near the surface where it is enlarged for receiving a knot 26formed in the elastic member 24:. Preferably, an ordinary rubber band isused for the elastic member 24, though if desired, some other form oftensioning member may be used, as for instance, an ordinary steelspring. hen the thread is in operative position, it extends through thespace partially enclosed by wall 8 and end 5 to the eyes or hooks 22 andfrom these eyes or hooks to the eyes 7 and "from thence to the goodsbeing woven. These parts are so arranged that when a new quill is put inthe shuttle the thread of the new quill will automatically move to theposition shown in Figures 1, 2 and 7 as the shuttle is operated. Vhenthe shuttle is moved to the left as shown in Figure 1, the thread willbe caused to move beneath the end member 5 and over the plate 9 to themember or prong 10. When the shuttle moves back in the opposite.direction, the thread will be pulled so as to engage point 11 and thenslip off so that it may quickly move to its finished threaded positionas shown in Figure 2. It will, of course, be understood that this actionmay be done manually if desired. In automatic looms it is usuallyperformed automatically as the loom discharges an empty quill andreceives a full one.

What I claim is 1. In a take-up and guide for shuttles, a take-upstructure for maintaining a thread under a certain tension and at thesame time taking up the slack comprising a plurality of pivotallymounted tension fingers having substantially hook-shaped ends, resilientmeans for moving said tension lingers in one direction, a pair ofco-acting guiding fingers projecting substantially at right angles tothe tension fingers and acting to guide the thread to the take-upstructure, means for guiding the thread to said tension fingers, andmeans forming an eye for guiding the thread from said tension fingers.

2. In a take-up and guide for shuttles, a plurality of swinging armshaving substan tially hook-shaped upper ends, the openings in the hooksfacing. downward, means aetlng as a spring for resiliently holding thearms 111 a given position, a plurality of fingers projecting betweensaid arms at a point below the hooks, said lingers acting to guide athread to a point against the arms below the hooks, and means forguiding the thread as it is being moved to a threaded position so as tostrike said fingers and move thereover to a point against the take-upstructure.

3. In a take-up and guide for shuttles, a take-up structure including abody having a top plate provided with a pair of dependmg guiding membersat one end, means coacting with said depending members for guiding athread to a given point, a takeup structure for receiving the thread atsaid given point, said bod-y being also formed with an outlet eyeprovided with a projection extending from near the entrance point of theeyelet toward said guiding members.

4:- In a take-up and guide for shuttles, a guide structure including abody having a top plate merging into a pair of spaced de pending guidingfingers, a plurality of auxiliary guiding fingers extendingsubstantially parallel to the top plate and co-acting with the firstmentioned guiding fingers. and means forming an outlet eye for thethread. said means including an extension extending into the eye forpreventing accidental removal of the thread.

I 5. In a take-up and guide for shuttles, the combination with a shuttlehaving a cut-out portion merging into a notch in one side of theshuttle, .said notch having one curved edge, of a guide structureprovided with a curved edge mating with the first mentioned curved edge,said guiding structure being formed with an outlet eye having anentrance slot, one edge of the slot merging into the curved edge of theguide, a takc-up structure arranged within said. socket, and

means extending from the guide for guiding a thread during the threadingaction to a point engaging the take-up structure and to said eye.
